[REQUEST] PerWorldPlugins

I want a plugin that can negate (disable) plugins and commands on certain worlds, with a command like /plugin negate <plugin> <world> and /command negate <command> <world>. This plugin disables the plugin on a world to make it seem as if it weren't downloaded. The plugin is meant to keep players in worlds from viewing/using/experiencing things with commands/plugins on one world when it is meant to be used in another.
